` SPECIFICATION :lorrning` part of Letters Patent No. 709,198, dated September 16 1902. l Application led June 24. 1901. Serial No. 65,810. (No model.) v

To all whom it 'may concern: vented, this resultbeing occasioned by reason Beit known that I, MAX BRAMSON, a subof the fact that the wick is raised always ject of the Czar of Russia, and a resident of to a determined height and maintained at the city of Warsaw, Russianv Poland, in the such height throughout the operation of the 55 5 Empire of Russia, have invented certain new burner and the necessity of first heating the `and useful Improvements in Petroleum In burner or burner-tube is avoided. I obtain candescent-Light Burners, of which the folthe results desired by the burner construction lowing is a full, clear, and exact description, which will now be described. reference being had to the accompanying Figure lis a vertical sectional view taken 6o 1o drawings, forming part of this specification. through my improved burner with portions My invention relates to a burner for use shown in elevation. Fig.II is a top view of upon petroleum-lampsto produce an incanthe cap that surmounts the cone of the burner. descent or white light in the operation of said Fig. III is a view, partly in elevation and burner; and the invention consists in feapartlyin vertical section,of the cap shown in 65 I5 tures ofinovelty hereinafter fully described, Fig. II.

Fig. V is a cross-sectional view heretofore in use showdefects, which it is the taken on line V V, Fig. IV. Fig. VI is a top object of my invention to overcome. In orview of the burner-cone. Fig. VII is a View 7c y zo der to produce a'biue flame in a burner of in elevation and partly in section of the the class named, it is requisite that the wickburner-cone. Fig. VIII is a sectional View tube be first heated by means of the ordinary of a modification of the burner. yellow petroleum-flame, which operation rel designates the lamp-font, which is proquires at least three or four minutes. The vided with an outer wick-tube 2 and an inner 75 z 5 blue flame that is then obtained must be carewick-tube 3, the inner tube 3 being of less fullyregulated, which requires practice and height than the outer tube, as clearly seen patience. After the burner has been heated, in Fig. l. during the periodv of the accomplishment of i 4 is the wick, positioned between the inner which the light effect has ,been raised or lowand outer tubes 2 and 3. 8o 3o ered, the body of the mantle of refractory 6 is a perforate air-distributento which `material utilized to produce the incandescent air passes through the font.

The burner also beertures lO. The neck 9 of the cone is provided comes heated to such a degree that it cannot with an interior liange 1l, that rests upon the be touched without burning the hands, and upper end of the outer wick-tube 2 and is 9o- 4o by reason of the `incomplete consumption of adapted to serve as a stop for the wick 4 to the petroleum the lamp emits an unpleasant limit the elevation thereof and prevent the and at times an unhealthy odor. i'lame burning from the wick from being di- The faults and `defects above enumerated rected upwardly, but instead causing the are entirely removed in a burner constructed iiame to burn at the side of the wick and in 9|: "45 in accordance withmy invention, inasmuch a, direction toward the air-distributer 6. as the construction of my burner is such that Above the flange 1l is an annular shoulder the blue flame is immediately obtained and 2 Within the cone-neck 9, and on this shoulsustained, and consequently complete comderissupported aring13,composedof material bustion of the petroleum is maintained of greater heat conductivity than the burner, roo 5o throughout the operation of the burner from suchas copper, and from which the heat rethe start and blackening of the mantle is preceived thereby is readily deflected to act in conjunction with the air-distributer 6 in turning the products of combustion of the petroleum into gas.

14 designates a conical cap having a central opening 15, that tits over the upper end of the cone-neck 9, while the lower end thereof seats upon the annular shoulder 8 of the cone 7. A

18 is the chimney, mounted on the cone 7.

In the wall of the vcone-cap 14 are a series of apertures 16, through which heated air from the interior of the chimney enters the mixing chamber A between the cone-cap and the cone 7 to mix with the fresh air that enters said chamber through the apertures 10 inthe curving part ot' the cone. It will be seen that these two cones or caps form a member having an air-mixing'chamber. The two currents of air will become mixed in said space, pass upwardly and through apertures 17 in the top of the cone-cap 14 to mix with the blue flame produced in the operation of the burner. By the introduction of air in this manner in a mixture of heated and fresh air an air-current is produced that enters into contact with the blue Haine in such manner as to avoid cooling or overheating of the burner.

19 designates the refractory mantle, the lower end of which fits over the cone-cap 14 and which is supported by a post 20.

In the practical use of the burner the wick is rst raised to the annular flange 11, as seen in Fig. I, and on the removal of the cone 7, with the parts of the burner associated 'therewith, the oil in the wick is ignited. The cone, together with the other part-s of the burner carried thereby, is then replaced, and the ame burns at the side of the wick, being projected toward the distributer The dame mixes with the air which enters through the perforate air-distributer and extends upwardly, contacting with the ring 13, of readily-heated material, and also mixes with the current of air that enters the interior of the mantle 19 from the mixing chamber A through the apertures 17 in the cone-cap 14. By 'this arrangement the blue ame is produced initially and maintained, and it is unnecessary to regulate the wick at any time during the period that the lamp is in use. The burner remains cool throughout its use, and the petroleum is entirely consu med,there by avoiding the production ot' disagreeable odors.

In Fig. VIII, I have shown a modification wherein the cone-cap 14a isnot Vapertured at its upper end, but is provided with the apertures 16a in its wail. In this form of construction the ring 13, of easily-heated material, is mounted nupon thecone-cap 14St instead oi" upon the neck 9 of the cone. The air enters the space between thecone and the cone-cap through the perforations 16al in said cap and through the perforations 10a in the cone and passes inwardly between the ange 12a and the upper end of the cone-cap and ring 13a directlyto thedefiector a'and through air and an outlet for the mixed air communicating with theinterior of the mantle.

2. In a burner of the class described, the combination with a chimney,'a Wick-tube, and a mantle, of a pair of apertured caps forming a detachable member, which is supported upon the upper end of the wick-tube, and has an air-mixing chamber receiving fresh and heated air, one of said caps being provided with apertures through which the air passes from said mixing-chamber to the interior o said mantle. A
